IMPROVED AUTOMATIC BLAST FOR CARBURETERS IN RAILROAD-CARS, &c.

Specification forming part of Letters Patent No. 59,226, datedlOctober 30, 1866.

To all whom t may concern:

Be it known that I, ELIAs S. HrToHINsoN, of the city and county of Baltimore, and State of Maryland, have made a new and useful Automatic Blast for Garbnreters in Railroad- Cars, Src.; and I do hereby declare the following to be afull, clear, and exact description of the nature, construction, and operation of the same, suflicient to enable one skilled in the art to which it appertains to construct and use the same, reference being had to the accompanying drawings, in which- Figure l is an end elevation. Fig. 2 is a side elevation. v

My invention consists of apendulum so suspended from an axis as, under the lateral or swaying motion of the car, Src., to operate a pump-rod through the lnedium of a crank or otherwise, and thereby afford a blast of air to be driven through a carbureti'ng-chamber, to be therein impregnated with hydrocarbon vapor and fitted to serve as an illuminating-gas or for the purpose of heating the car.

The object being to provide an illuminatinggas for the lighting or heating of the car, carriage, steamboat, or other vessel, the requisite blast of air through the carbureter'is obtained from a metal wheel or other air-forcing apparatus, such as an air-pump whose pistons are worked by the motions ot' a shaft, from which is suspended a pendulum which has a reciprocatin g motion generated by the swaying of the car.

In the drawings, D represents the bed or floor of a railroad-ear; E, the roof, and F rods or supports depending from the latter. Journaled in bearings G is a shaft, A, to which is attached the pendulum-rod C B. The lateral movement of the car causes the pendulum to sway from side to side, the motion being communicated, by means of the rocking lever H,

to the piston-rodsT T, Whose pistons JJ, working in air-pump cylinders K K, force a blast of air through pipes L L into the carbureter M, which may be of any required construction, and from which pipes lead to the burners or heaters in the railroad-car. l

Vhen the car, carriage, or vessel is in m0- tion its lateral movements will cause the pendulum to oscillate from side to side, and each motion will have the effect of causing one or other of the air-pumps to discharge a blast of air into the earbureter, or it may be collected in a receiver, where it forms a reserve for the sup ply of the burners or heaters while the carriage or vessel is not in motion. In either case it is the motion of the structure in which the pendulum is suspended which, acting upon the pendulum, supplies the motor generating the blast.

The same device may be made to operate fans, to increase the comfort of the passengers directly or to aid in the ventilation of cars.

The form or character of the air-com pressin g apparatus is not an essential feature of my invention,.whicl1 consists of a mode of utilizing the swaying motion of the moving structure bythe suspension of a weight or pendulum whose axis is connected to air-fannin g machinery of some kind.

Having described myinvention, what I claim therein as new, and desire to secure by Letters Patent, is-

A pendulum suspended in a railroad-car, carriage, or vessel, and applied, in connection with an air-pump, bellows, or compressor, to furnish a blast to a carbureter, substantially as described and represented.
